 # Periodic-Table-JSON
 A json of the entire periodic table. Feel free to use it in your projects.

-Temperatures such as boiling points and melting points are given in degrees kelvin.
-Densities are given in g/L and molar heat in (mol*K)
+Temperatures such as boiling points and melting points are given in degrees kelvin.  Densities are given in g/L and molar heat in (mol*K)
 Information that is missing is repersented as null. Some elements may have an image link to their spectral bands.
-All elements have a three sentence summary from wikipedia. Currently the color tag is useless, so please use appearance instead.
 
-Electron shells are given as an array, the first item is the number of electrons in the first shell, the 2nd item is the number of electrons in the second shell, etc...

+**Electron configuration** is given as a string, with each orbital separated by a space.  **Electron shells** are given as an array, the first item is the number of electrons in the first shell, the 2nd item is the number of electrons in the second shell, and so on.
+
+Both **ionization energy** and **first electron affinities** are given as the energy required to *detach* an electron from the anion.  Ionization energies are given as an array for successive ionization energy.
